I struggle with tequila to this day from a much similar experience.
The drunkest I ever got was one day when I came home from work, I had a full bottle of Cuervo in the cabinet. I figured I'd have a little night cap; 2 or 3 shots.
2 or 3 turned into damn near the whole bottle and when I woke up the next morning my upstairs neighbor was lying next to me naked. To this day, I still have no idea how exactly it all went down and how I talked her into bed but it took me a good hour to crawl to bathroom, I was throwing up on the way in a backpack that was lying next to my bed.
Horrible experience.
